HENRY CHENAULT, OF ALLENSVILLE, KENTUCKY.

BANK-CUTTING ROAD-MACHINE.

Application filed June 29, 1918.

To all whom it may concern Be it known that I, HENRY CHENAULT, a citizenof the United States, residing at Allensville, in the county of Todd andState of Kentucky, have invented new and useful Improvements inBank-Cutting Road-Machines, of which the following is a specification.

This invention relates to a bank cutting road machine, and one object isto provide an apparatus designed to be employed in widening a road whichmay extend between banks or elevations, and which apparatus shallinclude a blade member carried at one side of the machine and adapted tobe thrown to a suitable angle with reference to the direction of draftand with reference to the bank to be cut away.

A further object is to provide an apparatus comprising a framework orthe like mounted upon suitable supporting wheels and a blade supportingdevice comprising a member rotatable on an axis extending transverselywith reference to the main axis of the framework, with means forchanging the position of the blade in a vertical direction.

A still further object is to provide in connection with a suitablesupporting structure, a member under the control of an operating leverand adapted to swing on an axis extending longitudinally of thesupporting structure. a rotatable head under the control of said leverand adapted for operation through the arc of a circle of which said axisis the center and means carried by the head for supporting a bladedirectly operating upon the bank of earth to be cut away.

In the accompanying drawings:

Figure 1 is a top plan view.

Fig. 2 is a view in side elevation.

Fig. 3 is a transverse section.

Fig. 4 is a section longitudinally of the machine, and is taken on aline intersecting the axles and the bearings which support the blademounting devices.

Fig. 5 is a detail in perspective of the blade holding device.

Fig. 6 is a detail directly supportin the blade and adapted to bemounted in tfie device shown in Fig. 5.

The rear axle 10 is mounted on wheels 11 and 12 and carries a bolster 9suitably secured thereto. The front axle is pivotally Specification ofLetters Patent.

mounted with reference to bolster 14, and the element last mentioned andthe bolster first named are each provided with socket portions forreceiving the ends of short shafts or the like designated 13 and 13extending from pivotally mounted member 15 which carries the blade andoperating means therefor. The front wheels are shown at 15 and 16.

Extending between the king bolt 18 and the rear axle is a reachdesignated 20 carrying suitable mounting means for an upstanding member21 comprising a plurality of mem ers parallelly arranged and serving toguide a lever 22 for operating the blade carrying mechanism. Alongitudinal bar 23 curved as shown is secured at the points 24 and 25and is further secured to the parallelly arranged members between whichthe lever mentioned operates.

The lever 22 extends through the body portion of the member 15 andprovides for the rotatable mounting of a head or the like designated26,upon which a blade is mounted.

The blade holder shown at 27 is provided with suitable upstandingdevices 28 for the purpose of connecting the bail 29 which in turn ismounted on the under side of the head 26. A curved and U-shaped guidingmember 30 accommodates a laterally extending arm 31 and permits of thepivotal movement of the blade with reference to the head. The blade 33shown in operative position is provided with a toothed edge, but in Fig.2 I have shown a blade provided with a straight edge for use when theconditions demand an implement of that character.

A bail shaped arm 32 permits of the rotary movement of the head on itspivotal mounting and provides means for changing the angle of the bladewith reference to the bank of earth being operated upon. A movement ofthe blade at an angle to the direction of movement above named issecured by means of the lever 22.

Suitable bracing devices are employed where required, certain of thesedevices being designated 35, 36, 37, 38 and 39, and they serve toconnect the reach with the other elements shown, and to connect thelaterally extending plate 19, secured to the reach, with the rearbolster and with the corresponding element at the forward portion of thevehicle. The braces may be of strap -iron sufliciently heavy for thepurpose intended.

Blade 33 is detachably and adjustably secured to the blade holder 27 bybolts 34. The lever 22 is secured in adjusted position by means of bolts5 passing through theparallel members of U-shaped device 21, and the armor lever 31 is adjustable with reference to the guiding member- 30 andis secured by a bolt 8. In order to retain the head 26 in position forresisting heavy strains, I provide means for securing the elements 26and 15 rigidly together as by bolts 26'.

The tongue 40 is connected by means of a bail 41 with a bolster 14'carrying a plate member 42 coiiperating with plate member 43 carried bythe front axle. These circular plates are apertured as shown and aremaintained in any desired position with reference to each other by meansof bolts on the like 44. The connection of the tongue with theintermediate bolster 14' produces a draft in a direction for maintainingthe front wheels in positive contact with the surface of the roadway,and when the plates 42 and 43 are in adjusted positionso that bolster14' is at an angle with the front axle, the line ofdraft will be in adirection tend. ing to force the blade into positive contact with thebank being cut away.

What is claimed is:

1. In a--device of the class described, a supporting structure includinga plurality of axles, wheels carried by said axles, mechanism forcutting the side of a bank adjacent to the path of travel of the device,and comprising a member mounted to rotate on an axis extendinglongitudinally of the supporting structure, a member rotatable on themember first named, means for controlling the rotary movement, means forcontrolling the movement of the member first named upon its axis, andblade supporting'means carried by the-second named member.

2. In a device of the'class described, a supporting structure, mechanismfor cutting the side of a bank adjacent to the path of travel of thedevice, and comprising a member mounted to rotate on an axis extendinglongitudinally of thesupporting structure, and a blade carrying devicerotatable on the rotatable member first named, said bladecarryingfi'device projecting laterally from the supporting structure.

3. In a device of the class described. a supporting structure includinga plurality of axles, wheels carried by the axles, mechanism for cuttingthe side of a bank adjacent to the pathof travel ofthe device, andcompr1s1ng a blade mounted at one side of the supporting structure,means for rotating the blade on an axis extendinghorizontally andtransversely of said structure, and means for moving the blade on anaxis .extending longitudinally of the structure.

4. In a device of the class described, a supporting structure includinga plurality of axles, wheels carried by the axles, mechanism for cuttingthe side of a bank adjacent to the path of travel of the device, andcomprising a blade carried at one side of the supporting structure andnormally extending longitudinally thereof, means for changing theposition of the blade to an angle with reference to the transverse axisof the supporting structure, and means for changing the verticalelevation of the blade, said means last named including an elementrotatable 011 an axis extending longitudinally of the, supportingstructure, a lever extending transversely of the supporting structureand of the blade, and a second lever directly connected with the blade.

5.
